Ruben Fiszel 6e42633643 fix(pg): actionable error when s3object input exceeds jsonb 256MB cap (#10228)
Native SQL PostgreSQL scripts with an `(s3object)` input materialize the
whole referenced file into a single jsonb parameter. PostgreSQL hard-caps a
jsonb value's element payload at 256MB, so a large file fails with an opaque
`total size of jsonb array elements exceeds the maximum of 268435455 bytes`.

`materialize_s3object_args` now reports the largest materialized payload, and
that specific server error is rewritten into guidance explaining the input is
materialized (not streamed) and pointing large-file users at DuckDB, which
reads S3 natively and streams.
